MOGOOD USB C to Dual USB C Female Adapter, Type-C Data Splitter, Not for Monitor and Charging, Incredibly Durable, Super Fit, 5V/0.9A Power Output

UPDATE 09-2023: I acquired another USB-C device (Insta360 Link camera), and I tested this splitter using that device. The camera works as expected with either female connector, so this is NOT a defective product. The fault lies elsewhere--my motherboard is >5 years old, so probably has a 1st-gen USB-C connector that is causing the problem. I've updated my rating to be fair to the seller. Disconnected my WD My Book Duo from the USB-C connector on my computer, and put this in its place. When I connected the external drive to this splitter, it is not visible to my Windows 10 machine. I tried both female connectors, and neither appears to work. Removed it and reconnected my external drive and it showed up again. Perhaps its defective. If I decide to expend the energy to replace it instead of refunding, I'll update this review with the new results.

So I bought these originally, before reading fully (my mistake) to have a way to still have USB C access while using a USB C display. I realized the description said they won’t work for that. Okay, cool I’ll keep them just in case it was my mistake after all. No big deal I thought. Nope these don’t even work at all. Just tried these on multiple devices to split power and data. Doesn’t even show it’s plugged in on my PC or handheld devices. Poor quality considering I’ve not used them once and they both don’t work. I’m not concerned about a refund or anything, but wanted to share my experience.

Excelente calidad

This cable splitter works for its intended purpose but you need to fully read the description to be sure this is what you need. This splitter will not charge, and it will not work in any application where power delivery (PD) is required for operation. This is for data transmission only. Can of beans for scale.

This item does NOT work with a charger...I knew that going into it and it didnt matter to me, so I am totally happy with my purchase, but wanted to let others know just in case they were wondering...I mostly use it for a wired mouse and a flash drive for my Galaxy tablet, and for that it works PERFECT!!

on and off fails

it do not work with my samsung galaxy but it worked with my LG q7

This cable can’t be used for charging or for a monitor, that was understood, but the description says “5V/0.9A Power Output” which means it should be able to power a portable SSD without issue. That is not the case. I tried this cable with two different drives, three different cables, and none worked. The SSD worked as expected when plugged directly into the Macbook. The cable did work with a powered external HDD, so it appears this cable doesn’t supply power as advertised. Note, I was only attempting to use one of the female ports at a time, neither side was successful.
